Calling-hour rules for 457

Hours are local time at the person you are calling. When federal and Louisiana rules differ, the narrower window governs; the live check applies every row at once.

Conflicting location information: if the collector's information indicates the consumer may be in more than one place (e.g. an Eastern-zone area code and a Pacific-zone address), it complies only by calling at a time convenient in all of those locations (Reg F comment 6(b)(1)(i)-2). A collector may not call at any time it knows or should know is inconvenient to the consumer (e.g. after the consumer says so), regardless of the 8 a.m.-9 p.m. default (15 U.S.C. § 1692c(a)(1); Reg F comment 6(b)(1)-1). No federal Sunday or holiday ban, but a consumer's statement that a day or time is inconvenient makes calls then unlawful.

General Election Day is included conservatively because R.S. 1:55(B)(1)(a) gives state employees that day off.

Exchanges and time zones

Every assigned exchange in 457 sits in Central time, so the area code alone settles the zone for a landline. Rate centers by exchange count:

Rate center	Exchanges

Overlay codes — same territory as 457, same rules: 318

Other area codes in Louisiana:

225 Baton Rouge
337 Lafayette
504 New Orleans
985 Houma

Why area code alone is not enough

Mobile numbers travel with their owners, and a ported number keeps its original 457 area code and exchange. A 457 number tells you where the line was assigned, not where the person is today.
Under Regulation F, when you know of more than one location for a consumer — a mailing address in one zone, an area code in another — the time must be convenient in every one of them. Use the address-state field above to add the zones you know about.
Call only when the window is open in every location you know about, and stop calling at times the consumer tells you are inconvenient, whatever the clock says.

Questions

What time can you call area code 457?

Area code 457 is in Louisiana, on Central time. Debt collection: federal — Presumed convenient 8 a.m.-9 p.m. local time at the consumer's location, any day. Louisiana: no separate hour rule. Telemarketing: federal — 8 a.m.-9 p.m. local time at the called party's location, any day. Louisiana: 8 a.m.-8 p.m., Monday through Saturday; no calls on Sundays or state holidays.

What time zone is area code 457?

Area code 457 is entirely in Central time. Clocks move for daylight saving time in March and November.

Can a debt collector call a 457 number on Sunday?

Neither federal law nor Louisiana sets separate Sunday hours for debt collection; the 8 a.m.–9 p.m. local-time window applies, and a consumer can tell a collector that Sunday is inconvenient.

Does Louisiana restrict calls on holidays?

Yes. Louisiana bars telemarketing calls on its legal holidays. This page lists the dates for the next 12 months.

Is the 457 area code enough to know the person's local time?

No. Mobile numbers move with their owners and ported numbers keep their area code, so a 457 number may belong to someone in another time zone. If you know other locations for the person, the call should fit the window in all of them.
